Do CalciGrubs need to be dusted with calcium?

CalciGrubs require no dusting with calcium powder because they contain all the calcium your pet needs. 

How to care for your CalciGrubs:

Our CalciGrubs are fed a high-quality, plant-based diet to make them as nutritious as possible for your pet. However, this does mean that they tend to grow and pupate faster than the ones from other breeders. For best results, make sure to keep your CalciGrubs cool (~55°F). When chilled properly, CalciGrubs last approximately 1 month.

The geckos and bearded dragon both seem to like them, first time purchasing them.
